We have very seldom reflected upon the fact that fear runs like a baleful thread through the whole web of our life from beginning to end. We are born into the atmosphere of fear and dread, and the mother who bore us had lived in the same atmosphere for weeks and months before we were born. We are surrounded in infancy and childhood by clouds of fear and apprehension on the part of our parents, nurses, and friends. As we advance in life we become, instinctively or by experience, afraid of almost everything. We are afraid of our parents, afraid of our teachers, afraid of our playmates, afraid of ghosts, afraid of rules and regulations and punishments, afraid of the doctor, the dentist, the surgeon. Our adult life is a state of chronic anxiety, which is fear in a milder form. We are afraid of failure in business, afraid of disappointments and mistakes, afraid of enemies, open or concealed; afraid of poverty, afraid of public opinion, afraid of accidents, of sickness, of death, and unhappiness after death. Man is like a haunted animal from the cradle to the grave, the victim of real or imaginary fears, not only his own, but those reflected upon him from the superstitions, self-deceptions, sensory illusions, false beliefs and concrete errors of the whole human race, past and present.
If fear produces disease, acute or chronic, suddenly or gradually, through the correlations existing between the spirit and the body, how can there be a genuinely and perfectly healthy man or woman in the world? There is none.
That fear does produce all kinds of disease, has been frequently observed and fully substantiated by the medical profession. Dr. Tuke, in his admirable book, "Influence of the Mind upon the Body," cites well authenticated instances of the following diseases as having been produced by fear or fright: Insanity, idiocy, paralysis of various muscles and organs, profuse perspirations, cholerina, jaundice, turning of the hair gray in a short time, baldness, sudden decay of the teeth, nervous shock followed by fatal anæmia, uterine troubles, malformation of embryo through the mother, and even skin disease—erysipelas, eczema, and impetigo.
We observe in this list that fear not only affects the mind and the nervous and muscular tissues, but the molecular chemical transformations of the organic network, even to the skin, the hair, and the teeth. This might be expected of a passion which disturbs the whole mind, which is represented or externalized in the whole body.
Dr. Tuke reiterates the fact which has been so frequently observed, that epidemics owe a great deal of their rapid extension and violence to the panic of fear which exists among the people. When yellow fever, cholera, smallpox, diphtheria, and other malignant diseases obtain a footing in a community, hundreds and thousands of people fall victims to their own mental conditions, which invite the attack and insure its fatality. When the disease was new and strange, as the yellow fever was to the interior in its visitation in 1878, when the doctors were not familiar with it, the nurses not trained to it, the people, having no confidence in its management, lost hope, their fears became excessive, and consequent mortality was frightful.
How does fear operate upon the body to produce sickness? By paralyzing the nerve centres, especially those of the vasomotor nerves, thus producing not only muscular relaxation, but capillary congestions of all kinds. This condition of the system invites attack, and there is no resilience, or power of resistance. The gates of the citadel have been opened from within, and the enemy may enter at any point.
What determines the specific nature of the disease which attacks a person thus prostrated by fear? Men are frequently prostrated by fear in storms or fire or earthquakes or accidents, and no disease results. It is because they have been not thinking and brooding over any special morbid conditions. But in an epidemic, say of yellow fever, the subjects connected with the disease are strongly pictured on the mind. They are talked of, read about, discussed and written about, until the mind is full of images of fever, delirium, black vomit, jaundice, death, funerals, etc. When such is the case, no microbes or bacteria are needed to produce an outburst of yellow fever. The whole mass of horrors already stamped upon the mind is simply reflected and repeated in the body.
"As a man thinketh, so is he," said Solomon. Thoughts become things, apprehensions take form and substance, and lo! the disease. In the height of his happiness and prosperity, Job permitted himself to brood in silent fear over the possibility of losses and misfortunes, and he had at last to exclaim, "The thing which I greatly feared has come upon me."
Sudden and great fears are not frequent. The fears of every day, the constant apprehensions and anxieties of life, which are really fears of impending evil, prey upon our vitality and lessen our power of resisting, so that any passing disease may be photographed on our minds and seen upon our bodies.
Fear is itself a contagious disease, and is sometimes reflected from one to another mind with great rapidity. It needs no speech or sign to propagate it, for by psychological laws we are just beginning to comprehend, it passes from one to another, from the healthy to the sick, from the doctor or the nurse to the patient, from the mother to the child. Thus malignant influences may be cast around us by even our best friends and would-be helpers, under whose baleful shadow, without our even knowing of its existence, we and our children may sicken and die.
